Pervert doctor's spy pens, watch and hidden camera revealed as he is sent to jail for eight years

The hi-tech spying kit of a pervert doctor who used a network of hidden cameras to record patients, friends and colleagues on the toilet is revealed today after he was jailed for eight years.

World-renowned hearing specialist Dr Lam Hoe Yeoh admitted seven counts of voyeurism, six counts of making an indecent photograph of a child, and one of possessing extreme pornography when he appeared at Croydon Crown Court in south London yesterday.

Sentencing him to the “substantial” jail term of eight years in prison today, of which he will serve five years before being released on licence, Recorder Warwick McKinnon described the offending as “nefarious and despicable”.

He said: “The sheer scale, the gravity, the ingrained and compulsive behaviour demonstrated by the offences is significantly important.

“You are considered a high risk to the public.

“(Had you not been caught), I have no doubt that this prolific offending on a hitherto unprecedented scale would have continued.”

Speaking outside court, police said Yeoh was “one of the most prolific non-contact offenders ever investigated”.

Victims as young as three were discovered on a secret stash of 1,100 images and video files hidden in Yeoh’s home in Garratts Lane, Banstead, following his arrest on April 14.

The 62-year-old from Malaysia, who is also known as Robin, was caught only when a tiny camera he fixed to a communal toilet at the privately-run St Anthony’s Hospital in North Cheam, south London, fell into view.

On it, shocked staff found images of themselves using the toilet, as well as footage inadvertantly capturing Yeoh fixing the device with Blu-Tack.

Prosecutor Peter Clement described the offending, on victims as young as five, as “sophisticated, organised, planned and long-running”, and said the renowned doctor “grossly abused” the high degree of trust placed in him.

He added: “The (voyeurism) offending was vast and beyond any previously investigated by the Met.

“His intention was sinister, indecent and criminal.”

The court heard the offending dated back to January 1 2011, but Yeoh’s behaviour is likely to have begun earlier as it would take another two years for police to examine the huge volume of files found on a range of devices.

Yeoh’s footage was captured using a network of devices including pen drives and camera-watches, before being saved to a hard drive and/or a USB. Voyeuristic films were found on both his home computer and his NHS work computer.

Mr Clement told the court the footage was labelled with “graphic descriptions” that included dates and names. One label included the description “front and back”.

When Yeoh was arrested, a USB hanging around his neck contained footage labelled “Cardiff Train Teenager”.
